Chinese researchers build 33.33%-efficient perovskite-silicon tandem solar cell via new passivation strategy - pv magazine Global

CAS-led researchers developed a peak-selective passivation strategy using aluminum oxide nanocoating to solve leakage issues in pyramid-textured silicon for perovskite–silicon tandem cells. The method is compatible with existing silicon manufacturing and enables high-efficiency, stable devices reaching around 33% efficiency.
